Floor mopping appliance

ABSTRACT

A mopping appliance for mopping floors with a damp pad or cloth, comprising a mopping roller enveloped by a mopping pad or a bandshaped floor mopping cloth which runs endlessly over rollers or from one to a second spool and bears on the working surface underneath a mopping shoe or roller. The mopping roller and its enveloping mopping pad or the band-shaped floor mopping cloth is intermittently advanced during the mopping operation to bring a previously unused portion of the mopping pad or mopping cloth into contact with the working surface at every or any selectable forward working stroke of the appliance.

FIG. 35 

1. A mopping appliance for mopping floors and the like comprising: elongate handle means; mopping roller means mounted at one end of the handle means; absorbent mop means extending around at least part of the periphery of said mopping roller means to be supported thereby such that a portion of said mop means is adapted to engage a floor or like working surface backed up by said mopping roller means, whereby when said appliance is drawn backward and forward across the floor said portion of said mop means is drawn backwards and forward in contact with the working surface to mop the working surface; spring drive means operatively coupled to advance said mop means; intermittent means operatively positioned for selectively locking said mop means and holding the mopping roller means against rotation during the mopping operation and advancing said mop means, said intermittent means being comprised of a double pawl engaging a ratchet wheel connected with said mopping roller means; and means operatively coupled for, during working strokes of said appliance, releasing said intermittent means to intermittently advance said mop means by said spring drive means during the mopping operation irrespective of the friction between said mop means and the floor and the pressure of the appliance on the floor, to bring a previously unused portion of said mop means into the position occupied by said first-mentioned portion of said mop means for engagement with the working surface.
 2. A mopping appliance according to claim 1, wherein said intermittent means is connected with an actuating handle at the other end of said handle means, said actuating handle being selectively operable automatically for releasing said intermittent means without extra movement or effort by the operator and without interruption of the mopping work, said double pawl, when operated by said actuating handle, limiting said mopping roller means through a preselected angle of rotation, whereby said mop means is moved on through a preselected length, irrespective of length of time or strength of effort of the working stroke.
 3. A mopping appliance according to claim 1, wherein said mop means comprises a mopping cloth band of finite length carried on two spools mounted in a cassette attachable to said handle means.
 4. A mopping appliance according to claim 3, wherein said magazine comprises a window between said two spools, said window being adapted to permit passage therethrough of said roller means to withdraw a loop of said cloth band from one of said spools, said loop extending around a portion of the periphery of said roller means, and washing and wringing roller means to press said cloth band against at least one washing and wringing roller means in a separate cleaning device when the magazine is removed from the mopping appliance.
